Tabletop Gaming Experiences are a form of traditional gaming that traditionally requires either models, illustrations, or a vivid imagination to fully benefit from. Technology can be used to supplement this, such as mobile or tablet applications to help visualise aspects of gameplay content. Augmented Reality technology has the potential to further enhance Tabletop Gaming; however, there is little research into how it can be used in the areas of accessibility and sustainability, whether by reducing the carbon footprint of producing these games or by enabling wider participation. Our research aims to explore these topics and answer the following questions: How is Augmented Reality currently being used in Tabletop Gaming Experiences? How can it be used to assist with accessibility and make Tabletop Gaming Experiences more available to a wider range of audiences? Can Augmented Reality be used to lower the environmental impact of producing and distributing these games? This paper seeks to review the existing literature on this topic to identify how existing research has explored these issues, and how their findings may inform future Augmented Reality research on Tabletop Gaming experiences that are both inclusive and environmentally sustainable.

Designing inclusive multimedia systems that meet diverse accessibility needs remains a complex challenge requiring iterative refinement and sustained collaboration with end-users. This paper presents an empirically grounded case study of an accessible Augmented Reality (AR) authoring tool project that integrates Design-Based Research (DBR) with Agile Scrum. By blending DBR’s iterative design experimentation with Scrum’s adaptive software development cycles, we designed and implemented a multimedia authoring tool for instructors with diverse accessibility needs. We document the best practices derived through iterative evaluation, such as early stakeholder involvement, the use of accessibility-focused user stories, and the alignment of research evaluation cycles with sprint reviews. The study also identifies key challenges, including balancing research and development goals, coordinating interdisciplinary roles, and maintaining an accessibility focus under compressed iteration cycles. We situate our contribution within prior DBR–Agile integrations, emphasizing its novelty in addressing inclusive system design rather than pedagogical interventions. The paper offers actionable insights and a validated methodological framework for human–computer interaction (HCI) researchers and practitioners seeking to design accessible multimedia systems by leveraging the complementary strengths of DBR and Agile Scrum.

Quantum image transmission is a critical enabler for next-generation communication systems, allowing for the reliable exchange of high-quality visual data over error-prone quantum channels. Existing quantum-encoding schemes, however, often suffer from limited efficiency and reduced robustness under noisy conditions. This work introduces a novel multi-qubit phase-shift keying (PSK) encoding framework to enhance both fidelity and reliability in quantum image transmission. In the proposed system, source-encoded images (JPEG/HEIF) are converted into bitstreams, segmented into varying qubit sizes from 1 to 8, and mapped onto multi-qubit states using quantum PSK modulation. By exploiting multi-qubit superposition and phase modulation, the scheme improves spectral efficiency while maintaining resilience to channel noise. The encoded quantum states are transmitted through noisy channels and reconstructed via inverse quantum operations combined with classical post-processing to recover the original images. Experimental results demonstrate substantial performance improvements, evaluated using peak signal-to-noise ratio (PSNR), structural similarity index (SSIM), and universal quality index (UQI). Compared to superposition-only approaches, the proposed method achieves up to 3 dB SNR gain for higher qubit sizes, while single-qubit encoding remains limited due to reduced phase utilization. Moreover, relative to classical communication systems, the proposed multi-qubit PSK scheme consistently outperforms across all tested qubit sizes, highlighting its effectiveness for reliable, efficient, and high-fidelity quantum image transmission.
